Some New Forms of Indo- Australian Noctuidae 425 



Dutch New Guinea : Mount Kunupi, Menoo Valley, Weyland 

 Mountains, 6,000 feet. November, 1920, to January, 1921, three ? $ . 



Although differing superficially in many points, this appears to me 

 to be almost certainly the true ? of Lasiopoderes pratti. 



18. Toxocampa costimacula Gn. avisignata subsp. nov. 

 $ , 47—50 mm. 



Differs from typical costimacula (Toxocampa costimacula Gn., " Spec. 

 Gen. Lep.," vi, p. 429 [1852] [Silhet]) in the larger size, the rather 

 larger antemedial costal dark spot and the more diffused discal spot of 

 fore wing. On the hind wing the postmedial line is rather more dentate 

 but less curved than in Indian specimens. On the underside the 

 terminal dark band on both wings is interrupted by a pale subterminal 

 band, which on the anterior third of fore wing is sharply denned, bent 

 inward before and outward behind SC 5 . In Indian specimens in coll. 

 Brit. Mus. the discal spot of fore wing above is scarcely joined to the 

 medial costal dark spot, but this difference seems scarcely to agree with 

 Guenee's description of the type. In Sumatra specimens these two 

 spots are conjoined and, viewed from the front, form a mark somewhat 

 resembling the head and neck of a bird. 



S.W. Sumatra: Barisan Bange, 2,500 feet, October to November, 

 1921 (C, F. and J. Pratt), five S $ . 



A single ? in coll. Joicey from Sarawak is somewhat intermediate 

 between typical costimacula and subsp. avisignata ; somewhat nearer 

 to the latter form except in size. A specimen in coll. Brit. Mus. from 

 Singapore appears rather to agree with the type-form. 



19. Fodina sumatrensis sp. nov. (pi. XXII, fig. 17). 

 $ , 44 mm. 



Appears to agree in structure and coloration with F. oriolus Gn. 

 (" Spec. Gen. Lep.," vii, p. 274 [1852] [Silhet]) except for the presence of 

 some red hair on the fore and mid tibia and slight reddish lateral hair 

 on abdomen in sumatrensis. 



Crown of head and base of antennal shaft pure white. Thorax with 

 two white lines, somewhat as in F. stola Gn. (" Spec. Gen. Lep.," vii, 

 p. 275 [1853] [India]). 



Basal area of fore wing marked nearly as in stola but with the dark 

 patch behind costa almost matching the ground-colour of wing and
